Check engine light 850 1995

My check engine light has been on for several weeks now. I checked the codes and came up with the 2-4-1 code. I've cleared it several times but it keeps coming back. The weird thing is that I've taken a couple of long trips (@300 miles) with the AC running and the light has cut off towards the end of the trip, has stayed off for a day or so, then returned. Anybody have any thoughts about what's going on? I thought that once on, the light should stay on.

Thanks.

    The EGR is dirty. A long trip probably cleaned itself up a little and turned off the code. A couple of low rpm trips got it dirty again. Clean it and it will go away.

    Many of the codes will turn off the light when the condition changes for the better. Fix the problem before the CEL burns out.
